'I'O ALL WHOM IT MAY CONCERN: I

Be it known that I,- GE'ORGE K. OSBORN, of Brooklyn, in the county ofKings, and State ofv New York, have invented a new and improvedLamp-Burner; and I do hereby declare that thelfollowing is a. full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to thedrawings, forming part of the speci'ication.

This invention relates to a.' newand luseful improvement in'lamp-burners of thatolass which is designed for burning coaloil andother hydrocarbons, which require a large amount of oxygen in order tosupport ycombustion for illuminating purposes.

The invention consists in the application of a jacket suspended over thewick-tube, constructed and arranged in such. a manner that a largeamount ofx-th'evapor'or gas which is generated by theheat of the flameis mixed with air before it is brought in contact with. the ame, and at`the same time it prevents the heat of` the dame' v.frompassing to thelamp, as hereinafter. fuliy shownjaud described. In the accompanyingsheet of drawings- Figure I is a vertical section of a burner withmyimprovement attached to it, XX, iig. 2 indicating the line of section.

Figure 2, a plan or top view. Fignre, an oblique view, Y Y, iig. 2,4showing line of section. Similar letters of reference indicate likeparts. A represents the wick-tube of a lamp-burner. B is a jacket whichsurrounds the tube A. l C is a short tube fastened to the top of 'thejacket B,'through which the wick passes to the top.

D D are small passages t'o conduct the mixture of vapor and air from thejacket B to the top of the tube C; Part of the vapor formed inthe tube Cpasses into the jacket B, between the tube a and tube c, and there mixeswith the air which-'passes in at the bottom of the jacket I3'. This'mixture is then conducted through thc passages D D to the flame.

E isla perforated disk, by which my attachment is suspended over thewick-tube A, insulating the heat ftomdirect communication with the lamp,thereby lessening the danger of euplosion.

' The above description and-accompanying drawings represent my mostapproved -plan of forminghthe jacket YB, t-,ube C, and passages D D, butthe passages D D cangaiso be made of dctachedtubes, and the jacket B andtube C can be formed together of the same piece of metal.

i This invention has been practically tested, and has been found toanswer a goed purpose, causing the ilame to burn with a white light,like that fro'm'agas-jct, no c'ensivc smell or odor being emitted.

Having thus described my invention, I claim as'now, and desire tosecureby Letters Patent-- l The combination of the jacket B, surroundingthe wick-tube A, the tube C placed a little above thc wicktubeA. and thepassages D Drunnin'g from thebottom to'the top of the tube 0,'allarranged as and for the,

purposes specified. u
